OBJECTIVE To use fingerprint combined with hierarchical clustering analysis (HCA), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) to identify chemical patterns. METHODS Chrom Core 120 C18 (4.6 mm×250 mm, 5 μm) chromatographic column, 0.1% phosphoric acid aqueous solution (A)-acetonitrile (B) as mobile phase for gradient elution, volume flow rate of 0.8 mL·min-1, detection wavelength of 280 nm, column temperature of 30 ℃ injection volume of 10 μL, HPLC method was used to establish the fingerprints of 30 batches of medicinal herbs from 12 origins, and similarity analysis, HCA, PCA and PLS-DA were used and other chemical pattern recognition technologies were used to screen and quantitatively analyze the differentially characteristic components. RESULTS The fingerprinting method established by the established fingerprint method met the methodological requirements, and 17 common peaks were indexed by HPLC fingerprint of 30 batches of Pterospermum chinensis, with a similarity of 0.863-0.975. HCA, PCA and PLS-DA were used to distinguish the PH from different origins, and combined with the previous experiments, three components, protocatechuic acid, proanthocyanidins B2 and epicatechins, were comprehensively analyzed and screened as the active ingredients of the PH, and the content ranges were 0.103-1.676, 0.141-5.556 and 0.144-3.381 mg·g-1, respectively. CONCLUSION The fingerprint of the medicinal materials and the determination of the contents of the three active ingredients established in this study are stable, reliable and reproducible, which provides a certain scientific basis for evaluating the quality of Pterospermum heterophyllum.

目的 采用指纹图谱结合聚类分析(hierarchical clustering analysis,HCA)、主成分分析(principal component analysis, PCA)和正交偏最小二乘-判别分析(orthogonal partial least squares discriminant analysis,OPLS-DA)等进行化学模式识别,对翻白叶树药材指纹图谱数据进行分析,筛选特征性指标成分并以此建立翻白叶树有效成分的定量分析,为翻白叶树质量控制提供科学依据。方法 采用ChromCore 120 C18(4.6 mm×250 mm,5 μm)色谱柱,以0.1%磷酸水溶液(A)-乙腈(B)为流动相进行梯度洗脱,体积流量0.8 mL·min-1,检测波长为280 nm,柱温30 ℃,进样量10 μL,HPLC 法建立12个产地30批药材翻白叶树的指纹图谱,运用相似度分析、HCA、PCA 和 PLS-DA 等化学模式识别技术对差异性特征成分进行筛选,并定量分析。结果 建立的指纹图谱方法符合方法学要求,30批翻白叶树HPLC指纹图谱标定17个共有峰,相似度在0.863~0.975;通过聚类分析将不同产地翻白叶树分为3类,聚类分析与主成分分析结果一致;通过 HCA、PCA 和 PLS-DA 较好地区分各产地翻白叶树,结合前期实验,综合分析筛选原儿茶酸、原花青素B2及表儿茶素3个成分作为翻白叶树有效成分,含量范围分别为0.103~1.676、0.141~5.556、0.144~3.381 mg·g-1。结论 该研究建立的翻白叶树药材指纹图谱及3个有效成分含量的测定方法稳定、可靠,重现性好,对评价翻白叶树的质量提供一定的科学依据。
